Earthquake Surface Ruptures: what do they tell us about earthquake processes?

Event Type:

Seminar

Event Date:

30 May 2017

Venue:

EOS Seminar Room - N2-01B-28

Speaker:

Yann Klinger

About the speaker:

Yann Klinger defended his PhD in 1999 at the University of Strasbourg and then spent two years as a post-doc at Caltech.

Yann was hired as junior CNRS scientist at IPGP in 2001. In 2007 - 2008 he was invited professor at Harvard University in the solid mechanics department and in the earth science department. In 2011 he became senior CNRS scientist at IPGP. Since 2013, he has been head of the tectonics group at IPGP, with 11 faculty members and about 25 students.

Yann's main interest is in large continental earthquakes, earthquake ruptures, rupture mechanics and earthquake cycle. To address these issues I mainly use earthquake geology, tectonics and satellite image processing.

About the event:

During the last decade, high-resolution satellite imagery has changed our vision of earthquake ruptures. The easy availability of images from almost anywhere in the world, almost instantaneously allows for detailed mapping of earthquake ruptures as well as measurements of displacement with unprecedented accuracy. The current resolution, below one meter, offers new ways to map main ruptures as well as secondary breaks and damage zones that were out of reach earlier. Building on a set of examples including past and recent major continental earthquakes, we show how such a gain in mapping accuracy and extent opens new insight on the earthquake rupture processes
